Unit 5 Assignment
[Instructor Name]
[Date]
Composite patient written as a model document. Recommendations were checked on [date]; they should be rechecked before use, since they are revised.
Timeline, Ages 52 to 80
Colorectal cancer: 52 to 75. Grade A from 50 (US Preventive Services Task Force, 2021a).
Lung cancer, annual low-dose CT: 52 to 59. Grade B (US Preventive Services Task Force, 2021b).
Prediabetes and type 2 diabetes: every three years while his BMI stays at or above 25, through 70. Grade B (US Preventive Services Task Force, 2021c).
Hepatitis C: once, now. Grade B (US Preventive Services Task Force, 2020).
Prostate cancer: 55 to 69, an individual decision. Grade C (US Preventive Services Task Force, 2018).
Abdominal aortic aneurysm: one ultrasound between 65 and 75, because he has smoked. Grade B (US Preventive Services Task Force, 2019).
Why Each Starts and Stops Where It Does
Colorectal. The 2021 update lowered the start age to 45 because incidence was rising among younger adults and modeling showed benefit from earlier screening; it ends at 75 as routine, with screening from 76 to 85 made selective, because the gain shrinks as competing risks rise.
Lung. He has 27 pack-years and quit at 44. The recommendation covers adults 50 to 80 with at least 20 pack-years who smoke now or quit within the past 15 years. His eligibility therefore ends at 59, fifteen years after his last cigarette, because the balance of benefit against false positives and radiation shifts as his risk falls.
Diabetes. His BMI of 29 places him in the covered group; testing repeats every three years if normal.
Hepatitis C. A one-time test for adults 18 to 79, since most infections are silent.
Prostate. Grade C means the balance of benefit and harm is close for men 55 to 69, so screening is a decision made with him after discussing false positives and overtreatment, not a recommendation against.
Aneurysm. A single ultrasound in the window from 65 through 75 for any man with a smoking history, because the benefit is concentrated there.
What Does Not Apply, and Why
Routine screening with PSA before 55, or with electrocardiograms or whole-body scans, is not supported by the Task Force for someone like him. Blood pressure screening and lipid assessment continue as part of routine care. This schedule belongs to a composite patient; another man's history would change several lines. The schedule will be reviewed at each annual visit, and sooner if he resumes smoking, which would extend his lung screening window.

How this NU470 Unit 5 example is structured
When is the timeline's question; why belongs to the paragraphs beneath it. Each screening gets a short entry in the same order: the recommendation and its grade, the population it covers, what makes this man eligible, and the reason behind the age boundaries. The why is the analysis. Colorectal screening begins at 45 in the 2021 update because incidence was rising in younger adults and the Task Force weighed modeling of benefit and harm across start ages; lung screening ends fifteen years after quitting because the balance of benefit against false positives and radiation shifts as risk falls. Grade C for prostate screening is explained as a close balance requiring shared decision-making, not a recommendation against. What does not apply, and why, fills the last section, including tests commonly offered without Task Force support, and states that the schedule belongs to a composite patient.

NU470 Unit 5 questions, answered
Which guideline source should a screening schedule use?
The USPSTF is the usual anchor for adult preventive screening, and many rubrics expect it by name. Specialty societies such as the American Cancer Society sometimes differ on ages or intervals; where they do, say so and state which source the schedule follows. Whatever the source, record the publication year and the day you verified it.
Why does lung screening stop when someone quits?
Under the 2021 USPSTF recommendation, eligibility ends once a person has not smoked for fifteen years, because risk declines after quitting while the harms of repeated scans, false positives and incidental findings remain. That makes the quit date part of the calculation. A schedule that ignores it can keep a patient screening years past the point the evidence supports.
Can the sample's schedule be applied to a real person?
No. It belongs to a composite man and illustrates how an analysis is built and reasoned; it is not advice for anyone. Screening decisions for a real person depend on a full history and a conversation with their own clinician. Your assignment should apply the recommendations to the patient your prompt describes.
